When Stuart Griffiths left the army he found himself homeless. He is now an acclaimed documentary photographer. We join Stuart on his latest, most biographical work to date, his subject - the treatment of soldiers on 'civi street'.

In the UK there exists a 'duty of care'. A duty which Britain acknowledges it owes to its armed forces. Known as the military covenant, it is an unspoken pact between society and the military that dates back to the reign of Henry VIII, and which was formally codified as a 'covenant' in 2000.

The 'duty of care' to troops includes paying towards physical and mental healthcare, access to accommodation and also the provision of support for bereaved families. Yet out of the 25,000 men and women that were discharged from the military services in 2007, it is estimated that 10 per cent will live on the poverty line and face homelessness. To date there is over 230 veteran aid charities operating in the UK.

In November 2007, Lieutenant-Colonel Stuart Tootal resigned from the British army over "the governments appalling treatment of the troops".

Sir Richard Dannatt, the head of the British army, said his troops felt "devalued, angry and were suffering from Iraq fatigue". He went on to say "the military covenant is clearly out of kilter".

People & Power follows Stuart Griffiths, a veteran who became homeless after leaving the armed forces and who now works as a photographer raising awareness for veterans who feel that the military covenant and the government's duty of care is not being upheld.
